The Neckinger is a subterranean river that rises in the south of Southwark, near Walworth[citation needed] and flows to the Thames underground.
The community began the development of the marshes surrounding their abbey at Bermondsey, cultivating the land and embanking the riverside into a Priory Close spanning 140 acres of meadow and digging dykes.
[2] John Stow, a 16th-century English historian and antiquarian had the following to say about the area, "In the south end whereof[n 1] was sometime a priory or abbey of St. Saviour, called Bermond's Eye[n 2] in Southwark, founded by Alwin Childe, a citizen of London, in the year 1081."
He set Bill Sikes's den at the east of Shad Thames in buildings adjacent to St Saviour's Dock.
St Saviour's Dock is also featured as a more faithful recreation in the 2020 video game Watch Dogs: Legion, depicted as 'Butler's Wharf Houseboats'.
